In addition to that, he also has a Legacy heavy weapon engram for sale.

“These Engrams contain Year One Exotics (at Year One Attack and Defense levels) for players who want to finish up a Collection. They strongly bias towards Exotics not already in your Blueprint Collection, to help fill in the blank slots – excluding Mythoclast and Necrochasm, which are still only available from their Year One sources.”

In addition to the above, Xur is selling the stealth drive, plasma drive, heavy ammo synthesis, three of coins, and his newest item, glass needles. You can also exchange strange coins for motes of light if you wish.
